; means is provided within. the. control of the operator, through the medium of a readily acces-- sible lever, for adjusting the length or angle or degree of oscillation of the upright impeller shaft and.f0r settingof the parts to a position in which oscillation of the shaft is stopped, thereby 1 permitting the starting and stopping of the oscillatory movement of the agitator and allowin 3 minute adjustment of the length or degree of swing when the parts are set'for oscillation ofthe i impeller.

In the adaptation of the invention illustrated vin Figures 1 through 6, ,the tub I, substantially circular in plan, has a side wall 2 and a bottom wall 2, and this tub is mounted and supported on legs 4, an enclosing case structure I being preferably provided around the tub and substantially 1 concentrically following the contour of the side wall 2. A bearing sleeve I is mounted to rise sub stantially centrally within the tub i as a housin around an opening through the bottom of the tub, and agitator shaft 1 is mounted in a bearing 8 at its upper end for oscillatory movement within the housing, the upper end of this agitator shaft "preferably extending above the bearing I sleeve I. An agitator l is mounted on suitable bearings In on the sleeve 0 to be capable of oscillatory movement within the tub, and this agitator is provided with a portion H engaging with and holding upon the upper end of the oscillatable agitator shaft 1 sothat as the shaft I is oscillated the agitator will be carried therewith to have a similar oscillatory movement. Further, as the f degree or angle of oscillation of shaft I ls in- 1 creased or-decreased the movement of the agita- 1 tor 0 will be accordingly varied and. as shaft 7 is stopped the agitator will also be stopped.

A pitman rod 29 has one end thereof connected at the eccentric bearing IS; in consequence of which thepitman will be continuously operated duringrotation of the drive gear .or eccentric means ill. The pitman rod has its free end extending adjacent to the oscillatable agitator Shaft II.

operating link 3| pivo'tally connecting on the end of the pitman 28 at 32 has a hearing at its re--'- maining end pivotally connected at with the extending oscillating arm or means 30. An arcuate control link is pivotally connected with the pitman 2! on the axial center as at 32, of the pivotal mounting of the operating link 3!, and this control link 34 hasa bearing 35 at its swinging and spaced adistance substantially corre-.

sponding to the distance of the bearing 32 from the pivotal mounting at 32.

' A control and setting lever 26 is swingably mounted by stub shaft 31 oscillatable in a bearing 38 on the gear case 13, and on its inner endv this stub shaft 21 carries a radially extending The adjusting arm is -'pivota'=tlly connected with the bearing 25 of adjusting link 34 by pivot means ll. As shown in Figs. 2 and 3, this operating and control lever 36 projects through a peripheral- 1y extending slot or opening 4| provided through the wall 01'. the casing I; and this opening M is provided on one side with serrations or notches and with toothed-formations 42 providing a plurality of stops for the adjusting lever 36. whereby this lever is held in desired adjusted positions.

With the. structure as; shown, the operating lever 28 can be made sufficiently flexible to permit ele-- vation for disengagement from the tooth-like .detents 42 and the lever can then be freely swung to any desired position of adjustment. Upon re- I lease, the operating and control lever will fit into oscillating link and the control link and the eontrol lever. and connecting parts is perhaps best or. setting of the parts is illustrated in Fig. 5;

When operating or control lever It is swung or moved to bring the axial center of the bearing at I. more nearly into substantially axial alignment with the center of the bearing ll; the de ree or length of the oscillatory'impiils'e imparted to the eachlating means 31 will be shortened. When the axial centers ofbearing portions it and "are brolllht into axial alignment, as illustrated in.

Pig. 6, the two-links will swing or pivot around this coinciding axially aligned center as the, common bearing connection at 8! is moved by the pitman 2!, in consequence of which the agitator shaft 1 will not have any'oscillating force or movement applied thereto, To insure that the agitator shaft I, and consequently the agitator 0, will remain stationary'dn the stoppedeposition of the parts. a stop N extends radially with re- I spect to the stub; shaft )1 and-has .a face'presented to engage with; a portion or the linkage, or with some other portion, whereby the shaft 1 is held in the stoppedposition and against casual oscillating impulses or forces or movement. This 7 stopped position or setting of the parts is illustrated in Fig. 8, audit will of course be understood that the control or operating lever II can be set to and will be {retained in any position intermediate the extreme-settings as illustrated in Figs. 5 vand 6 to adapt; the parts for a greater or lesser degree of oscillatory'movement pr swing of the agitator. 1 j (Zonsequeniilm with the parts as illustrated and described the movement of the agitator can be gradually started and gradually stopped and the parts can be set so that the agitator can be 080111 lated or operated through any desired length or angle of oscillation as may be consideredsuitable or desirable for the-particular materials being washed or particular. conditions under which the machine is being operated. In the starting and stopping'and the operation with any desired degree of oscillation, motor and the drive eccentric. means are continuously operated and there is no Jerking or severe strain upon the agitator or the operating F irts or the control means as the controls are actuated for starting and stopping and for adjustment of the movement or degree of oscillation of the asitator.

with the segmental rack teeth"; of the rack moved so that oscillatory movement asoaass her or oscillating means will be stopped in consequence of which the agitator shaft 1 will also be stopped and will not impart any oscillatory force tothe agitator 0. Obviously, the structure as disclosed in Figs. 7 and 8 permits of ad- Justment of the control means to various settings oi the parts so that the oscillating means will start and stop oscillatory movement of the agitator shaft I, and consequently the agitator, and will impart controlled oscillating movement to the agitator through any length or degree or angle of oecillation between the two extremes of settings In Figs. 9, 10 and 11 of the drawings Ihave illustrated another modified construction which in several respects lends itself particularly well to manufacture and to embodiment in a commercial washing machine. The gear casing has the lower end of the agitator shaft ll extending thereinto, anddrive gear Ii i revolubly mounted with-' in the gear casing at a point spaced away from the agitator shaft II. An oscillating arm I! is on theag'itator shaft I to extend substantially radially therefrom and is provided with a bearingl opening at itsouterswinging ,end. A

control and setting arm It extends substantially radially from a stubshaft is mounted in a bearing ll formed in the gear casing so that the stub shaft is substantially axially aligned with the agitator-shaft II, and this control and setting arm is has a bearing pinor member I! carried at the outer end thereof and spaced from the axial. center a distance corresponding substantially to the distance between the axial center of the agitator shaft" II and the center of the bearing opening of the oscillating arm II. The stub shaft It has its lower end extending beneath the casing II and a control and setting lever I1 is connected on this extending end to beavailable to oscillate the stub shaft is and consequentlyswing the control and setting arm II. An arcuate link is is swingably' connected at one end at the bearing ofthe oscillating arm 52, and

a second arcuate link I! is pivotall connected at one end with the control and setting arm ll.

These-two arcu'ate links II and I have bearings at their outer ends and the spacing between the bearings at "the ends of the, two links is substantially equal. A pltman rod Cl is connected at one end at an eccentric bearing ll of vthe drive gear II, and is extended toward the location of the parts as grouped around the agitator shaft ll. At its extending end, the pitman ll is connected with the extending ends of the two arcuate links II and is through themedium oi a bearing pin", or in any other suitable manner. The

' ilar part, is carried by the casing structure in member u. The itmanis' has the oscillating link II and thecontroi' link ll oscillatably or swingably mountedthereon at a common center, a

With this modified constructiom thecontrol and setting lever II can be manually moved to adjust the control and setting arm I! to the positions shown in Figs. 9 and- 10 and to any position intermediate. When the parts are in the adjusted relation illustrated in'l 'ig. 9, the arcuate links I. and It willhe'movedoroperated through the connection with'the pitman I between the positions as shown by thefull-and the:dotted lines. and in consequence the oscillating arm I! will be movedandoscillatedpthrough an angle considerably more thanonehalf of a circle, thus e imparting wide angle oscillatory movement of will establisha-substantially leakproo'f connection the agitator shaft 55 and consequently to the agitator carried or actuated by or from this shaft I. When the control and setting lever 51 is "thereof ensaging'with the stop'lug or pin 64. With the axial centers .of the pins 56 and 82' aligned, the arcuate links 58 and I! will move or 1 swing in substantially the relation. as indicated-. by the full and the dotted lines andin conse--- quence there will be no movement imparted or mediate the two extremes as'illustrated in Figs. 9 and 10 respectively, and in consequence the control. and setting arm 53 will be adjusted to I transmitted to swing the oscillating arm 52. In

' this adaptation, the control and. setting leverjl can be equated to any desired position intergive or impart greater or lesser swinging move- I ment to the oscillating arm 52.

As stated, the embodiment of my invention illustrated in Figs. 12 through 15 may be a preferred form, and may prove best adapted to commercial manufacture and most practical in use and performance. With thisadaptation, the tub and agitator and the supporting and other main. structural features may be substantially the same as described above. The gear casing 65 has the drive gear GI revolubly mounted therein and meshed to be. rotated by .dr'ive pinion 61. The

drive gear 6' can in turn be meshed with'a' become readily loosened or worn or damaged through long continued use. This agitator shaft can be extended upwardly, in the manner as hereinbefore'described, through the bottom of the washing machinetub and can have the a tator mounted thereon substantially in the manthrough the bottom of the casing so that the low'er portion of the casing can, be employed to receive andretainalubricant. in

A control and setting shaft :18 is fitted in suitable bearing to have ,a portion thereof within' the gear case '5, and an operating arm 19 is fixed upon andextends substantially radiallyfrom this controland setting shaft ll. A- tOBE link 30 swingably connected at oneend' with the endof: the operating arm 19,.and this toggle link at its other end is swingably connected with the fulcrum and adjusting member 12, as at 8|, The fulcrum and adjusting member has a bearing 82 thereon which-upon swinging movement of saidmember 12 will be moved to substantially center with the axis of bearing II at the outer end of the operating arm IL: A control and settin lever 84 is fixed to and extends radially fromthe control and setting shaft II with its outer end disposed to be readily available to the user-or}; operator of the washing machine so that this control and setting lever can be manually swung to move the fulcrum and adjusting member)". from the position shown in Figs. 12 and 13 to the. neutral position shownin Fig. 14,-or-to any op crating position; intermediate these two extremes.

A pitman rod. ll extends from; an eccentric bearing 85' of the drive gear 66 tohave its free agitator shaft 89, and this end oi the pitman rod is provided with bearings i6 and I. Anioperather set forth, or in any other way that will be best suited for the particular construction and conditions of use. An operating arm II' is fixed to and extends radially from the oscillatable agitator shaft '1, preferably in the upper part of the gear casing I, and a fulcrum and adjusting member I2 is swingably mounted within the lower part of the gear case at awpoint separated from the shaft 01 and on the side thereof away from the drive gear '8. This fulcrum member is of somewhat segmental shape and is swingably or oscillatable on a bearing stud I; mounted in a suitable bearing 14 of the gear casing. As here shown, the bearing stud It is formed externally on a long taper and the opening of the bearing I4 is correspondingly formed. A bolt 15 extendsupwardly throughan enlarged bore in the bearing stud II and a spring 16 received around the bolt bears between the head'of this bolt and the lower end of the enlarged recess of the stud bearing portion II; with a washer l1 seated against the lower end of the bearing portion "holding the bolt 15 against upward thrust, and in this manner the bearinsstud Ills resiliently urged Fig. 14 will bring the bearing 82 thereof closer ing link I! having bearingsat its wo ends is connected swingably at one end with the bearing of the pitman rod and at its remaining end with the bearing 83 of the operating arm H. A ful crum link 88 having bearings at its opposite ends is fitted to the bearing 81 of the pitman rod 85 and the bearing 82 of the fulcrum and adjusting member 12.

As the mechanism is illustrated in Figs. 12 and '13, the fulcrum and adjusting member is moved to one extreme, or to the position where maximum oscillatory movement will be-imparted by the pitman rod and the linkage to the agitator shaft 89, and in this relation the toggle link 80 is set on substantially dead center so that the parts will be substantially held and retained against accidental or casual displacement or readjusting. When the parts are moved. to the other extreme position, being the neutral position as illustrated in Fig. 14, the toggle link 80 is in folded relation and it is then desirable to have a stop extending upwardly from the bottomoi the casing 88 to engage with the fulcrum and adjusting member to retain this member against excessive movement. In this neutral adjustment, it is desirable that the axial center lot the bear ing stud 13 substantially coincides with the axial center or the bearings It and 81 when the pitman a rod 8! has attained its full movement to one extreme position, and consequently the stop 90 may well be madeadjustable as by being mounted eccentrically on a clamp bolt, as indicated at 9|. Obviously, rack or retaining means for holding the control and settinglever at in adjusted positions can be provided, perhaps somewhat after the manner as described above,'o'r in any other suitable form.

with this construction of the parts. the movement or setting of the fulcrum or -adjusting member from the position shown in Figs. '12 and 13; through the neutral position as illustratedv in to the neutral position, and in consequence'the pivotal connectim for the, fulcrum link will 1 9 I be so adjusted that the operating link ll will swing the operating arm ll through an angle of lesser degree, thereby shortening the oscillatory movement. of the agitator shaft II. The maximum operating setting is shown in Figs. 12

g and 13, and the twoextremes of movement are illustrated in these views. When the parts are set for the neutral or inoperative position, as illu'stratedin Fig. 14, the operating arm II will be swung to a position with the bearing 88 thereof perpendicularly'aligned with the bearing 82 of the fulcrum and adjusting member 12, in consequence of which the operating link II and the fulcrum link a will be simultaneously swung around this same axial center between the full and dotted line positions shown in Fig. 14, withmeans pivotally out moving or swinging the operating arm ll,

ings separated so that as these two links are actuated through the pitman rod 86 movement will be imparted to swing the operating arm II and consequently oscillate the agitator shaft '0. Ob-- viously, the fulcrum and adjusting member 12 can be set to any desired position'between the two extremes and the degree or angle of oscillation of the agitator shaft 60 will be correspondingly varied. This particular embodiment of the invention will lend itself well to manufacturing methods and procedures, and the structure when in use will operate smoothly and with precision thereby preventing undue wear upon or damage to any of the parts and insuring quiet operation of the washing machine throughout along period to life and utility.

While I have herein shown and described only certain specific embodiments of my invention and have suggested only certain other possible modiflcations or embodiments, it will be appreciated that the linkage or operating connections can be varied in other manners, and that changes in the form and construction and connection and association of the parts can be made to accomplish the desired function without departing from the spirit and scope of my invention.
